Opinion | Elizabeth Warren: We Can Prevent More Bank Failures

Had Congress and the Federal Reserve not rolled back the stricter oversight, S.V.B. and Signature would have been subject to stronger liquidity and capital requirements to withstand financial shocks. They would have been required to conduct regular stress tests to expose their vulnerabilities and shore up their businesses. But because those requirements were repealed, when an old-fashioned bank run hit S.V.B‌., the‌ bank couldn’t withstand the pressure — and Signature’s collapse was close behind.

On Sunday night, regulators announced they would ensure that all deposits at S.V.B. and Signature would be repaid 100 cents on the dollar. Not just small businesses and nonprofits, but also billion-dollar companies, crypto investors and the very venture capital firms that triggered the bank run on S.V.B. in the first place — all in the name of preventing further contagion.

Regulators have said that banks, rather than taxpayers, will bear the cost of the federal backstop required to protect deposits. We’ll see if that’s true. But it’s no wonder the American people are skeptical of a system that holds millions of struggling student loan borrowers in limbo but steps in overnight to ensure that billion-dollar crypto firms won’t lose a dime in deposits.

These threats never should have been allowed to materialize. We must act to prevent them from occurring again.

First, Congress, the White House‌ and banking regulators should reverse the dangerous bank deregulation of the Trump era. Repealing the 2018 legislation that weakened the rules for banks like S.V.B. must be an immediate priority for Congress. Similarly, ‌Mr. Powell’s disastrous “tailoring” of these rules has put our economy at risk, and it needs to end — ‌now. ‌

Bank regulators must also take a careful look under the hood at our financial institutions to see where other dangers may be lurking. Elected officials, including the Senate Republicans who, just days before S.V.B.’s collapse, pressed Mr. Powell to stave off higher capital standards, must now demand stronger — not weaker — oversight.

Second, regulators should reform deposit insurance so that both during this crisis and in the future, businesses that are trying to make payroll and otherwise conduct ordinary financial transactions are fully covered — while ensuring the cost of protecting outsized depositors is borne by those financial institutions that pose the greatest risk. Never again should large companies with billions in unsecured deposits expect, or receive, free support from the government.
